ON-VEHICLE CONTROL DEVICE AND ON-VEHICLE POWER SUPPLY DEVICE

WIPO Patent Application WO/2018/135331

A1

In the present invention, when a failure of a first power supply unit has occurred, the power consumption of a second power supply unit is suppressed and discharge current from the second power supply is increased according to a trigger. In an on-vehicle control device (2), a power supply failure detection unit (30) detects that power supply from a first power supply unit (91) has entered a predetermined failure state. A processing speed detection unit (33) sets, at least when the power supply failure detection unit (30) detects the failure state, a processing speed to a suppressed speed, and, when a trigger signal is generated outside while the processing speed is set to the suppressed speed, sets the processing speed to a speed higher than the suppressed speed. A control unit (31) is configured to operate at the processing speed determined by the processing speed determination unit (33), and calculates the duty of a PWM signal which is given to a voltage conversion unit (3), on the basis of a preset target value and the output value from the voltage conversion unit (3), and performs feedback control of outputting, to the voltage conversion unit (3), a PWM signal set to the calculated duty.
